HENRY RENSOH, OF QUINCY, ILLINOIS.

Fl RE-ESCAPE.

SPECIFICATION forming part of Letters Patent No. 308,279, dated November 18,1884.

Application filed September 13:4.

To aZZ "whom may concern:

Be it known that I, HENRY Bunsen, a citizen of the United States of America, residing at Quincy, in the county of Adams and State of Illinois, have invented certain new and useful Improvements in Fire-Escapes; and I do hereby declare the following to bee. full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to certain new and useful improvements in fire-escapes, the same being designed more especially as an improvement on my Patents No. 281,136, dated July 10, 1883, and No. 299,850, dated June 3, 1884.

My improvements in the present application consist in providing the pivoted arms with guides, which carry sliding arms having the roller attached thereto, as will be hereinafter fully set forth, and pointed out in the claims.

In the accompanying drawings, which illustrate my invention, Figure l is a perspective view; Fig. 2, a side view, partly in section; and Figs. 3 and 4, detail views.

A represents the window-casing; B, the pivoted arms, which are attached thereto; and D, a receptacle or box, which is provided with a hinged'i'ront and cut-away sides. The arms B are pivoted to the inner side ofthe windowframe, as shown at b, and integrally or attached tosaid arms near their pivoted portions is a stop or retainingcatch, c, a portion of which extends outwardly from the arm B at right angles therewith, and is thence bent so as to lie parallel with the main portion of the arm B, said portion being provided with a notch, 0, as shown. The end of the pivoted arm Bis bent over upon itself at (I, so as to provide aguideway for the sliding extension-arm C. These turned-over portions are preferably formed integral with the arm B, and at the end at the upper side of the arm is provided a springcatch, 6, the play of which is limited by. a stop, 0, the point of this catch passing through an opening on the upper side of the turnedover guide d, as shown. The opposite guide (No model.)

the escape rope or ladder; The sliding arm O has its outer end, g, bent slightly inwardly, and it is provided on its upper portion with a series of serrations, t, which are provided with straight and inclined faces, so that the same may be drawn in one direction past the hook or catch 0, but will be prevented from sliding in an opposite direction by the straight edges engaging with the hook. Below these serrations i the same edge of this arm is provided with a recess, 1', having straight edges, with which the hook or catch 6 will engage, so as to prevent the movement of the arm in either direction. By this construotion it will be seen that the arms 0 may be readily drawn outwardly and held in an extended position at any point desired, and that the entire removal of the arms will be prevented by the catch engaging with the recess t". The lower end of the sliding arm Cis provided with a portion, is, which is bent at right angles to the main body, and is adapted,when the arm Ois extended,to lie between the guides d d, and will serve to brace the same, and when the arms are slid one upon the other this portion 7; will lie within the recess 0 of the projecting portion a, formed on the bar B.

When the arm 0 is slid upon the bar B, and said arm turned 'so as to bring the roller within the box or receptacle, the gravity-catch f will engage with an inclined notch, Z, near the outer end of the arm 0, and preventthe roller slipping down while being carried to theboX. The gravity-catchesf will remain in engagement with these notches until the roller is turned so as to project out of the window,when they will automatically release themselves. If desired, the arm 0 may be provided with a longitudinal slot, as shown in Fig. 4, through which will pass guide pins or bolts attached to the bar B.

It will be readily seen from the foregoing that I provide by means of my improvement IOO side bars for the roller, which slide within each other instead of being pivoted, and which may.

be extended to any distance desired, and when extended held in such position.

1. In a fire-escape, the side bars, B, pivoted within the window-frame, and provided at its outer end with guides for an extension-arm, and catches for said sliding and extension arm, substantiahy as showlnand for thepurpose set forth.

2. In a fire-escape, the pivoted bars B, provided at their outer ends with guides d d, a spring-catch, e, passing through a perforation in one of said guides, in combination with the sliding; arm 0, provided with serrations t, substantially as shown, and for the purpose set forth.

3. In afire-escape, the pivoted arnisB B, having their outer. end turned upon itself, so as to fornrguides (Z (1, said guides being provided with perforations, through which passef, and a projecting portion, 0, in combination with the arms 0, provided with an outwardly-projecting portion, 75, serrations i t l, and recess i, the parts being combined and organized substantiaily as shown, and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

HI INRY RENSOH.
